I have been looking at the Bingo600 script above and have a few questions.
#1) Does avr-gcc have a homepage? The only one I can seem to find looks to be horribly out of date. (http://home.overta.ru/users/denisc/)
#2) Patches for GCC and Binutils... are they written by the maintainers of avr-gcc? Are patches valid from one version of gcc to the next? I guess it really boils down to is how do you know which version of GCC to use and how do you know which patches to apply?
I guess that is it, just general questions I have had about cross compilers for a long time now. I have been thinking about trying to build avr-gcc with gcc 4.2.0 and avr-libc 1.4.6 and just getting a feel for how I should do this correctly.
